Interesting. A thing that I've noticed is that most of the animated pictured will have the dialog mixed very well for some reason. I haven't watched Tangled but I've watched How To Train Your Dragon this weekend, and also some scenes have lots of surround going on and some crazy LFE, the dialog never looses intelligibility.
